More middle-aged and older adults are wearing soft contacts than ever.

And one of the biggest reasons they stop wearing contacts is the difficulty they face reading with their contacts after presbyopia begins to set in around the early 40’s.

Presbyopia is the diminished ability of the natural lens in our eyes to focus up on close objects. It begins with the occasional medicine bottle being a struggle to read and then over time more and more gets blurry. It can be very frustrating to stare at something up close and have it be blurry regardless of what you do.

So there are three basic choices a contact lens wearer can do to aid their reading while still wearing contact lenses.

Reading Glasses

Initially, the use of an over-the-counter reader or prescription reading glass for occasional use works well for people in the early stages of presbyopia. They are worn over distance contact lenses so there is little adjustment and vision is clear near and far. However, they need to be with you, not left in the […]

Recent Census Bureau data shows a population of approximately 70 million baby boomers (the generation born from 1946-1964). What does that have to do with low vision you may ask? Approximately 40 million people worldwide have some sort of blindness, and aging increases the incidence of macular degeneration and other vision impairment that qualifies them as “low vision” persons.

Low vision is a condition of the eye in which the vision falls below 20/70 in the better seeing eye. It impairs the recipients, rendering them unable to perform daily tasks that others take for granted. With this rising aging population, the awareness of low vision therapy, diagnosis, and treatments are more widely available.

Low vision treatment can help people recover from decreased visual function due to retinal disease, brain injury, neurological damage, and other causes.

It is not only the elderly population that is affected–approximately 20% of low vision patients are children under the age of 18. Childhood genetic disorders of the eye such as retinitis pigmentosa, albinism, Bests disease, ROP, rod/cone disorders, and glaucoma are […]

Age-related macular degeneration, often called ARMD or AMD, is the leading cause of vision loss among Americans 65 and older.

AMD causes damage to the macula, which is the central portion of the retina responsible for sharp central vision. AMD doesn't lead to complete blindness because peripheral vision is still intact, but the loss of central vision can interfere with simple everyday activities such as reading and driving, and it can be very debilitating.

Types of Macular Degeneration

There are two types of macular degeneration: Dry AMD and Wet AMD.

Dry (non-exudative) macular degeneration constitutes approximately 85-90% of all cases of AMD. Dry AMD results from thinning of the macula or the deposition of yellow pigment known as drusen in the macula. There may be gradual loss of central vision with dry AMD, but it is usually not as severe as wet AMD vision loss. However, dry AMD can slowly progress to late-stage geographic atrophy, which can cause severe vision loss.

Wet (exudative) macular degeneration makes up the remaining 10-15% of cases. Exudative or neovascular refers […]

What Is Intraoperative Aberrometry?

Yes, that is a mouthful, but the concept isn’t quite as hard as the name.

An Intraoperative Aberrometer is an instrument we can use in the operating room to help us determine the correct power of the implant we put in your eye during cataract surgery.

Cataract surgery is the removal of the cloudy natural lens of your eye and the insertion of a new artificial lens inside your eye called an intraocular lens (IOL).

The cloudy cataract that we are removing has focusing power (think of a lens in a camera) and when that lens is removed, we need to insert an artificial lens in its place to replace that focusing power. The amount of focusing power the new IOL needs has to match the shape and curvature of your eye.

To determine what power of lens we select to put in your eye, we need to measure the shape and curvature of your eye prior to surgery.  Once we get those measurements, we can plug those numbers into several different […]

For over 40 years the standard surgical treatment for glaucoma was a procedure called a trabeculectomy.

In a trabeculectomy, the ophthalmic surgeon would make a hole in the wall of eye to allow fluid from the inside of the eye to flow out of the eye and then get resorbed by the blood vessels in the conjunctiva (the mucous membrane that covers the white part of the eye).

This surgery often resulted in a large decrease in the Intraocular Pressure (IOP). Reducing the IOP is the goal of glaucoma surgery because multiple studies show that if you can reduce the pressure the progression of glaucoma slows.

The problem with trabeculectomy is that although it frequently lowers the pressure, it also has a fairly high complication and/or failure rate. This led to some reluctance to perform the procedure unless the glaucoma was severe, or the pressure was very high. As a result of those issues there has been a search during the last 40 years for something that had a lower complication rate and could be more easily deployed […]

Is it safe to use "Redness Relief" eye drops regularly?

The short answer is NO.

Here’s the slightly longer answer.

There are several eye “Redness Relief” products on the over-the-counter market, such as those made by Visine, Clear Eyes, and Bausch & Lomb – as well as generic versions sold by pharmacy chains.

Most commonly, the active ingredient in redness relief drops is either Tetrahydrozoline or Naphazoline. Both of these drugs are in a category called sympathomimetics.

Sympathomimetics, the active ingredient in redness relief drops, work though a process called vasoconstriction, an artificial clamping down of the superficial blood vessels on the eye surface. These blood vessels often dilate in response to an irritation. This increase in blood flow is trying to help repair whatever irritation is affecting the surface of the eye. Clamping down on those vessels by using a vasoconstrictor counteracts the body’s efforts to repair the problem.

The other downside to repetitively using redness relief drops is that after the vasoconstrictor wears off the vessels often dilate to an even larger degree than when the process started. This […]

The word “astigmatism” is used so much in the optometric world that most people have talked about it when discussing their eye health with their doctor.

“Astigmatism” comes from the Greek “a” – meaning “without” – and “stigma” – meaning “a point.” In technical ocular terms, astigmatism means that instead of there being one point of focus in the eye, there are two. In other words, light merges not on a single point, but on two different points.

This is experienced in the real world as blurred, hazy vision, and can sometimes lead to eye strain or headaches if not corrected with either glasses or contact lenses.

Astigmatism is not a disease. In fact, more than 90% of people have some degree of astigmatism.

Astigmatism occurs when the cornea, the clear front surface of the eye like a watch crystal, is not perfectly round. The real-world example we often use to explain astigmatism is the difference between a basketball and a football.

If you cut a basketball in half you get a nice round half of […]

There are several different variations of glaucoma, but in this article we will mainly focus on Primary Open Angle Glaucoma. This means that there is no specific underlying cause for the glaucoma, like inflammation, trauma or a severe cataract. It also means that the drainage angle where fluid is drained from the inside of the eye into the bloodstream is not narrow or closed.

Closed or Narrow Angle Glaucoma, which we won't be discussing today, is treated differently from Open Angle Glaucoma

In the U.S., Primary Open Angle Glaucoma (POAG) is by far the most common type of glaucoma we treat.

Glaucoma is a disease where the optic nerve in the back of the eye deteriorates over time, and that deterioration has a relationship to the Intraocular Pressure (IOP).  Most – but not all – people diagnosed with glaucoma have an elevated IOP.  Some people have fairly normal IOP’s but show the characteristic deterioration in the optic nerve. Regardless of whether or not the pressure was high initially, our primary treatment is to lower the IOP.  […]

Do you have family members with eye-related conditions?

The two main eye diseases in adults that have a genetic link are glaucoma and age-related macular degeneration (AMD).

Glaucoma is a deterioration of the optic nerve caused by pressure in the eye or poor blood flow to the optic nerve. It has no symptoms at its onset. In most cases if you wait to get glaucoma diagnosed until you begin to realize there is something wrong with your vision, upwards of 70% of your optic nerve will have already been destroyed. Once the nerve is destroyed there is no way of reversing that today and treatment is focused on trying to preserve whatever nerve tissue is left.

Your chances of getting glaucoma are four to 10 times higher if you have a close relative with glaucoma. Getting your eyes examined regularly is always important but even more so if there is a family history of glaucoma.

Macular degeneration is the leading cause of blindness in most of the developed world. It too can cause serious vision loss if […]
